To add a user or group
to an ACL resource, click Add ACL User in
the ACL Manager panel. In the Add Acl User window,
enter the user or group name in the User field.
Select the boxes that correspond to the default Read, Write, Alter,
and Control permissions that you want to grant. Then click Add.
The user is added and
the ACL listing is automatically updated. You cannot delete an individual
user or group from an ACL resource. To delete a user, you must delete
the entire ACL resource, and then add it, omitting that user.
